SECTION 1 GENERAL

1 IntroductionThe requirements for inspection and maintenance of safety equipment can be found in a large number ofstatutory instruments. Establishing an easy, user-friendly and practical overview of such requirements hasproven to be challenging.DNV GL intends to address this challenge and provides a compact and practical tool in the format of a list ofsuch requirements for ship owners and operators (“Users”) at the time of the issuance of the document. Thislist includes also requirements and recommendations by DNV GL and IACS.This document does not address additional or more stringent requirements from manufacturers and flagadministrations. Users must take these requirements into account.DNV GL reserves the right to amend the content of the document at any time.

2 ProcedureUsers may use this document to establish or validate inspection and maintenance routines in their PlannedMaintenance Systems. When establishing the maintenance and inspection procedures it should be noted thatcertain jobs may be performed by competent crew members, while others shall be performed by speciallytrained persons. It should also be noted that certain jobs needs to be scheduled to coincide with a relevantSafety Equipment Class survey. Which parts of the inspections and maintenance shall be completed bycompetent crew members or specially trained persons or attended by surveyor, are indicated in the list.

3 ApplicationThe document does not replace the original equipment manufacturer’s instructions and maintenancerequirements.It is not meant to replace or overrule any existing rules, regulations, statutory requirements or technicalstandards.Finally, it is not meant to replace Users’ individual responsibility to know the applicable requirements andensure compliance at all points in time.

4 PrecautionsAs a general rule, all inspections shall be carried out in accordance with the system manufacturer’sinstructions and safety precautions. If equipment is undergoing maintenance or testing, then suitablearrangements shall be made to ensure safety is not diminished through the provision of alternate equipmentor other measures.

5 RecordsRecords of the inspections shall be carried on board of the ship, or be accessible in digital format on board.In cases where the inspections and maintenance are carried out by specially trained persons other than theship’s crew, inspection reports shall be provided upon the completion of the inspections. Some inspectionsrequired by SOLAS shall be entered in the logbook.
